Decorating a teen bedroom and PB teen is too expensive!?

Hi! I am moving from one part of town to another and my mom (to cushion the fact that her boyfriend is moving in with us) said that we could buy all new bedding and stuff to redecorate or since its a new room completely i guess it would be just decorate, but my sister brother and I are all doing it and PB teen can get expensive like really expensive. I created a bed spread and that alone was like 500 dollars. Where can I buy bedding to go with a light and dark purple room with silver accents? I have a full sized bed if that helps. I need a store or website that has good cheap bedding and decor that is cheap and well frankly not like sketchy. if it is a website it needs to be able to shipped to ct and if it is a store then it needs to be in ct. Thanks so much!
